On Tuesday night, a racial barrier could fall in Georgia: If 12th District Democratic Rep. John Barrow loses to Republican state Rep. Lee Anderson, the Democratic party would lose its last white congressman in the Deep South, where other white Democrats have long fallen far into the rearview of this Republican stronghold.

Over in the 10th Congressional District, Republican Rep. Paul Broun -- who earned widespread scorn after calling evolution, embryology and the Big Bang theory “lies from the pit of hell” – is running unopposed; some Georgians have threatened to choose “Charles Darwin” as a write-in candidate in symbolic protest.
